I tried this today and only had a quick play but first impressions are, it took a while to load the first time, then seems to give a sort of combination of effects like cross process and instagram.
Not sure I'd get much use out of this if I'm honest, but I'll give it a better try over the next few days.

Well I've had a further play with it this evening and heres a pic treated with it using one of the presets.
Personally I won't be using it much, I do sometimes cross process or add a lomo type effect but I normally just use photoshop, but this looks more instagram style, not my cup of tea.

Update. I have managed to find a way of using the sliders on the original image, but theres a fairly limited range of ajustments, but better than nothing.
Still don't think I'll get a lot of use out of it though.
